cpu: Add a helper function cpu_get_lapic_addr
This change adds a helper function cpu_get_lapic_addr() that returns LOCAL_APIC_ADDR for x86. It also adds a weak default implementation which returns 0 if platform does not support LAPIC. This is being done in preparation to move all ACPI table support in coreboot out of arch/x86.
